  • Meets the highest technical requirements of animal labs.
  • Gas anesthesia procedures generally involve an induction phase and a maintenance phase. Easily covers typical animal lab requirements with:
    • 0-4 LPM or 0-10 LPM, high precision analogue flow-meters.
    • Vaporizer
    • Induction box and mask breathing circuit.
    • Chemical scavenger or flow hood.

 High precision, cost effective expandable system

  • Anesthetize animals of virtually any size (from mouse to horse) and up to 4 animals simultaneously (depending on model).
  • High-precision analog flow-meter with 2 different flow versions (0-4 LPM and 0-10 LPM) for different sized or multiple animal delivery.
  • Reliable and precise delivery of the anesthetic gas with new, TEC3 or TEC4 vaporizers for Isoflurane, Sevoflurane and others on request.
  • Compact and portable for easy transportation and storage. 
  • Rodent masks have latex diaphragm for correct positioning and continuous flow of oxygen and anesthetic. The membrane has a positive seal to reduce the investigator’s exposure to anesthetic gases. 
  • Modular and expandable for a cost effective system that suits your needs now and in the future. Select a basic system (flowmeter and vaporizer) or start with a full system (add induction boxes, breathing circuits with masks of any size, switch valves, delivery systems for multiple animals, active and passive scavengers, etc.)
  • Blue, thick aluminum rack has a highly resistant paint to protect against stains from aggressive anesthetic liquids & solvents.
  • Two universal attachment blocks are mounted on the back, to connect the device easily to rail or mobile floor model anesthesia rigs (25x8mm up to 35x10mm).

In the past decades, there has been a welcome increase in concern for the welfare of laboratory animal: increased use of Anesthetizing Systems is one of the results.

Anaesthetising laboratory animals is a significant improvement of research procedures, since it results in a lack of awareness of any potentially painful or distressing events: in fact, anaesthesia can be used to prevent pain during potentially painful procedures, such as surgery, or to provide a humane means of immobilising an animal for procedures, such as imaging.

When selecting a method of anaesthesia, it is important to consider the required depth and duration of anaesthesia and whether the method selected will cause the minimum of interference with the purpose of the research procedure. In addition the method of anaesthesia should ideally be simple to administer, without causing significant distress to the animal, free from undesirable side effects and allow a smooth and uncomplicated recovery.

Information on potentially suitable anaesthetic regimens can be obtained from a variety of sources, including the Named Veterinary Surgeon, and specialist laboratory animal anaesthesia and general veterinary anaesthesia textbooks.
